What is the sustained rate of fire (RoF) for the M4A1 Carbine in semi-automatic mode?

The sustained rate of fire for the M4A1 Carbine in semi-automatic mode is 45 rounds per minute (RPM). This rate reflects a firing mode where the shooter is engaged in deliberate, controlled shooting, allowing for aimed shots rather than rapid, uncontrolled fire.

In semi-automatic mode, each pull of the trigger results in one round fired, which is consistent with the goal of precision shooting inherent in the semi-auto function. The sustained rate of fire takes into account the need for the shooter to allow the firearm to cool and manage recoil, as firing too many rounds too quickly could lead to overheating and reduced accuracy.

Understanding the sustained rate of fire is crucial for operational planning and engagement scenarios, as it directly influences ammunition management and engagement strategies on the battlefield.
